Steel Grit

Steel Grit

Steel grit is angular in shape and is produced by crushing oversize steel shots and subsequently heat treated by tempering to get the required hardness and microstructure. These intrinsic characteristics of the product enormously enhance the performance of the blasting for heavy descaling, deep descaling and surface preparations. The angular shape and relative hardness of steel grit ensures rapid cleaning rates and excellent recyclability. With variations in hardness and size, steel grit can also be used for cutting granite and stones. The four standard hardness ranges for high carbon cast-steel grit are as follows:

 GS  : The hardness range from 40 to 51 HRC

GM : The hardness range from 47 to 56 HRC

GL   : The hardness range from 54 to 61 HRC
